390 stroker build advice

I, & a lot of my friends have built other brands of engines over here with cast iron heads in the 10-10.5:1 & all have run quiet happily. I also have access to a ready supply of a gas if I ever need it. This car is going to be more a street/show car than strip monster so the appeal of the thumpr for me is that it will turn heads at the show n shine but still be reasonably streetable. The car is going to look stock, like grandad drives it to church on Sunday, then start it & people wonder what the hell is making all that noise ? Can't be pops car. As long as it will scare the missus when I open it up & I can possibly run a mid to high 12 on the rare trip down the strip I'll be pretty happy
